CAN POSITIONING MECHANISM FOR LIQUID DISPENSING Filed Aug. 12, 1929 WITNESS: l N V EN TOR [hm 1 E 5 HAyarsv ATTORNEY Patented July 18, 1933 human srares PA'E'E crIAnLEs' rr.

thesuccessive cans are changing to a position beneath such liquid supply.

The object of the invention is to provide mechanism whereby vessels may be filled or partly filled with liquid in endless succession without starting or stopping the liquid sup ply means after the predetermined amount of liquid has been introduced into each vessel Another object of the invention is to pros vide means whichplaces thevessels in such relation one to the ot ier'that no liquid'will be spilled during the movement oi one vessel from beneath the liquid supply means and another vessel moved intov such position.

till another object is to preventthe liquid from spreading at the mouth of the liquid supply means andthereby dripping onto the machinery or floor.

Accordingto the inv'ention,the cans or vessels to be filled are provided with an annular ring or flange and the flanges otthe adjacent vessels have that portion which 0 passes beneath the liquid supply means overlapped so that during the change of one can,

from beneath said supply means and the adj acent can under sa1d supply means, the over- Ialls thereon into one or the other of said vessels, and therefore prevent the same from being spilled and wasted.

The liquid supply means contemplated by 50. Figure 1 is a side elevation showing the 6 is rotated"inthe'manner lapped flanges will direct any liquid which can feeding means and the hopper for directing the liquid into the vessels, I

igure 2 is atop plan view of the hopper showing the orifice at the bottom thereof through which the liquid passes into the vessels,and l g Fie ure 3 is a tragmentaryview of adj acent' nual flanges overlap at the point which passes it is notessential to the invention herein, as

other mechanism maybe incorporated in the machine and which will, with equal success,

perform the function of the mechanism shownl' v In the present invention the feed screw shown by my Patent. No. 1,459,492,,grantd June 19, 1923.

The cans are fed onto a table? andeach can is advancedintermittently bythe succeeding can striking the same when it is pushed from the end of the screw 6jso that. the time lapse between advancement of the cans allowseach can to remain under the orifice 8 of the hopper 9 just asuflicient time toreceive the desired amount of liquid. It therefore follows that the element 6 may be timed in its operation so that the predetermined amount of liquid will be placed in each of the which pass under said orifice. I i i The annular outwardly extending flange 12 at the upper end of the can or vessel 11 is of vessels 11 the same thickness as the materialv forming the can and slnce the edge thereof is rounded or substantially,chamfered when the flanges of two adjacent cans contact they will slide into a position substantially suchas shown in Figure 3 or in any event an overlapped flanged position. This, in the present in stance, is accomplished by the end of the shown at the end thereof over'against the 'worm or feeding means 6 pushing the can 1 As the cans en 'a e there is rovided the 1 space 13 snown in Figure 3 w hich passes un-- der the orifice through which liquid continually flows, and such liquid as fallsupon this overlapped portion of the flanges readily passes into one or the other of the cans whose flanges form this overlapping portion so that no liquid is Wasted by spilling during the time that one can is being moved from beneath the orifice and the succeeding can being moved to that position.

The hopper 9 is provided with a supply pipe; 14 having the cock 16 and regulating valve 17.

In the first place, when the machine is started an amount of liquid in excess of the amount which will pass through the orifice 8 is admitted-to the hopper until a certain desired level, indicated by the lines at 18, is attained, whereupon the regulating valve is adjusted to maintain that level. This provides a fixed head which insures each of the cans receiving the identical quantity or volume desired. i i

The bottom of the hopper is provided with a downwardly extending flange or ring 19 which prevents the liquid passing through the orifice from spreading out onto the plate 21, and the side of the hopper extending to wards the feed mechanism is provided with an upwardly curved plate 522 which prevents the cans from piling up and from engaging with the flange or ring 19 at the bottom of the hopper. I

Of course, the can filling mechanism illustrated herein may be modified in various ways without departing from the invention herein set forth and hereafter claimed.

The invention is hereby claimed as.fol lows :1. Mechanism for depositing uniform quantities of liquid in cans which have an upper annular flange, said mechanism comprising a stationary hopper adapted for con-.

depositing uniform quantities of liquid'in cans having an upper annular flange, said mechanism comprising a stationary hopper having a serving orifice in the bottom thereof for continuously serving liquid during the operation of said mechanism, means for automatically and intermittently feeding cans under said orifice, said means providing an overlapping of the segments of the flanges which pass directly under said orifice to prevent the liquid from spilling when a can is being moved into fill-. 111g position.

Mechanism for. depositing uniform quantities of liquid in cans, said mechanism compri ing a hopper having a continuously lowing orifice, means for maintaininga fixed level of liquid, in said hopper, means for automatically and intermittently feeding cans under said orifice, deflecting means on hopper to prevent the cans from being raised above a suitable position for receivin ingsaid orifice and extending toward the g the licuid charge, and a flange surroundlocus of the can and terminating in the-inter vening space. v

4. Thecombination-of a reservoir for can filling achines having a continuous discharge, means for feeding liquid thereto so as to maintain a fixed level therein, and a deflecting plate for preventing the cans from being thrown upward in their travel to a position under the discharge.
